A, acrylamide, deionized water are dropped in the reactor, stir 30 ± 5min at a slow speed, be warming up to 40 ℃;

B, open stirrer continuously, add iso-butylene and 2-hydroxyethyl methacrylate, be warming up to 60-65 ℃ then;

C, adding S-WAT stir at a slow speed, and reaction 30 ± 5min is warming up to 80-85 ℃ then;

D, adding disodium ethylene diamine tetraacetate stir at a slow speed, reaction 60 ± 5min;

84-85 ℃ of E, control constant temperature add ammonium persulphate, stir reaction 30 ± 5min at a slow speed;

F, be cooled to 70 ℃, add benzene emulsion, stir 15 ± 5min at a slow speed;

G, be cooled to below 45 ℃, after the assay was approved packaging final prod.

The present invention, it is simple to have production technique, characteristics such as cost is low, nontoxic, tasteless, non-environmental-pollution, saving resource, it is a kind of environmental type interfacial agents, be widely used aspect many in tackiness agent, coating, building decoration, fabric processing, sheet processing etc., have the bonding strength height, very strong perviousness is arranged, water-tolerant, advantages such as easy construction.Uses such as alternative putty powder, glue for tile, wallpaper glue, 107 glue.
